摘要： A practice ammunition includes a propellant case having a case body; a circumferential mouth part; and a circumferential shoulder connecting the case body with the mouth part. The shoulder tapers from the case body toward the mouth part. The practice ammunition further includes a bursting body having a rear part fitted into the mouth part. The rear part is provided with a circumferential groove including a relatively deep frontal groove zone and an adjoining, relatively shallow rear groove zone, whereby the groove is stepped as viewed in the direction of the longitudinal axis of the ammunition. There is further provided a holding ring so dimensioned that it is compressible such as to be fully receivable within the deep groove zone. The holding ring surrounds the rear part of the bursting body and is clamped between the rear groove zone and the inner surface of the shoulder, whereby the holding ring assumes a wedged state. In such a wedged state the holding ring has an outer diameter which is greater than the outer diameter of the rear part measured at a location axially rearwardly of the groove and is greater than the inner diameter of the mouth part.
摘要翻译：实践弹药包括具有壳体的推进剂盒; 圆周口部; 以及将壳体与口部连接的周向肩部。肩部从壳体向口部逐渐变细。练习弹药还包括具有装配到嘴部中的后部的爆裂体。后部设置有包括相对较深的前槽区和相邻较浅的后槽区的周向槽，由此当从弹药的纵向轴线的方向观察时，槽是阶梯状的。还设置有一个固定环，其尺寸被确定为可压缩的，以便可以完全容纳在深槽区内。保持环围绕破裂体的后部并且夹持在后槽区域和肩部的内表面之间，由此保持环呈楔形状态。在这种楔入状态下，保持环的外径大于在槽的轴向后方测量的位置处的后部的外径，并且大于口部的内径。
